Wilwood emergency/parking brake brackets

Recommended Posts

I started this project a few months ago after trying to buy a set of Woza's brackets, but since he stopped making them I had to do it myself.

 

Started off making the steel brackets to use the wilwood mechanical spot calipers (120-2280,2281) I made the brackets and mocked everything up. I was unable to figure out a way to stop the calipers from rattling (I hate rattles) so I scrapped that idea and decided to make a new set using wilwood's new MC4 mechanical parking brake calipers.

Made from 6061 aluminum, they are much lighter than my original steel design.

My brake hats are JSK hats which have a 24.5mm offset so the brackets should work with other kits that run the same offset.

 

I made the first set for myself, and am happy with the way they turned out. Would anyone else be interested in a set?

According to Z Fire, the AZC hats have a 24mm backspace/offset which is pretty close to my JSK hats.

 

It uses a Lokar universal ebrake cable also, which ended up being much cheaper than a custom cable. My stock/aftermarket ebrake cable reaches but I was unable to find the correct size Eclip to clip the cable into the caliper.

If anyone is actually interested in purchasing them, I can sell them for $300 US plus $20 shipping in Canada or US. That price is for both left and right brackets.

 

My machinist will make them but I require a minimum order of 5 people (10 parts).

I am in. I have the JSK rears and stupidly got rid of my parking brake mechanicals under the car. What would I need cable wise to get this to work? Can you confirm those are 12.2"x0.81" disks (my calipers are Forged Billet Superlites and look different than yours)?

 

Thanks for taking the lead on this.

I am going to talk to the machinist about making some more of these brackets.

 

They use the Wilwood Dynalite caliper and the MC4 parking brake caliper with a 12.2 inch 0.81 thick rotor

The ebrake cable I used was a Lokar cable (EC-80WU) meant for those wilwood calipers.

 

I will likely send the brackets out with a bunch of shims that will allow you to shim the bracket out for various different brake setups (AZC or JSK)

Haha..well well....

 

I remember you contacting me about my brackets !

 

I too hate the rattle that comes from the Spot calipers used in my kit, and also the pad area is VERY small, resulting in not a huge clamping force. They are constantly requiring adjustment too. In retrospect, I shoudl have used them for sometime before selling kts, however everyone simply 'had to have a set now' ! lol

 

I have been toying with the idea of re-designing using teh MC4 calipers, but you have spared me the work ! thanks !

 

So, in a nutshell...I WANT A SET ! haha....where are we at with numbers etc ?

 

Cheers

A word of caution.  Has this assembly been re-installed into the car and driven?  I made a similar assembly a few years ago (although it wasn't nearly this nice) using a Maxima caliper.  The problem that I had was that both the cable and the caliper interfered with the floor pan of the car on bumps.  I notched some, but it wasn't enough-the caliper still struck the bottom of the floorpan on some of the bumps at autocross.  I recommend that the strut assembly and brake be installed in the car and run thru its full anticipated travel range before we all jump on the bandwagon.  There appears to be plenty of room above the wheel when the suspension is hanging in full droop, but things get crowded really quick when the car is at ride-height, even more so when lowered and put into a bump.  All will be well IF the assembly is narrow enough to clear the floor pan.

I never bothered to make any more of these. When I first put them on here a lot of people showed interested, then after me spending time with the machinist, ironing out all the little problems, making my final prototype (which is installed on my car now)  no one wanted them anymore.

 

For me to do 3 sets, I'd loose money. 5 sets, break even maybe. So I don't see it as being worth the time/money I have invested. I got my set and that was all I was after.

 

Thanks to everyone who showed interest though.

Sorry to hear that these will not be available. I was excited to see that Wilwood had finally produced a good quality Handbrake-only caliper - I wish it was available when i developed my kit !. So, seeing as 05plsrt4 wont be producing anymore, I will definately be engineering a new set of brackets for my AZC setup. This will only start to happen though in a couple of months time as I have other projects/commitmenst on the go at the moment, but i look forward to getting the ball rolling and I will definaetly make the brackets available - after all, for me its not about making profit, its about sharing the knowledge.....
